Question

Four rods each of length 1 have been hinged to form a rhombus. Vertex A is fixed to rigid support vertex C is being moved along the x-axis with a constant velocity v as shown in the figure. The rate at which vertex B is approaching the x-axis at the moment the rhombus is in the form of a square is

  1. fraction numerator v over denominator 4 end fraction    
  2. fraction numerator v over denominator 3 end fraction    
  3. fraction numerator v over denominator 2 end fraction    
  4. fraction numerator v over denominator square root of 2 end fraction    

The correct answer is: fraction numerator v over denominator 2 end fraction
